Application of GIS Technology in Urban Planning Informatization

As a new information technology science in recent years, GIS plays an important role in urban planning industry, and its application is becoming more and more extensive and in-depth. At present, the application of GIS technology in urban planning informationization mainly embodies in the aspects of database platform construction, information comprehensive service, three-dimensional assistant decision-making and dynamic monitoring of planning, etc. The main shortcomings and application prospects of GIS technology are studied and analyzed, and the urban digital planning system based on GIS technology is preliminarily established. The establishment of GIS-based urban planning platform is inseparable from the modeling of known geographical phenomena, that is, the completion of the establishment of geographic data model, which also involves the object-oriented method. The application of GIS technology has helped solve many problems encountered in urban planning and design, changed the situation that planners relied excessively on subjective experience to guide and guide the planning work, and made planning and design have more scientific and quantitative analysis methods for urban planning and construction. Have important reference value.
